This expression was finished to its own unique playlist which is blasted to the barrels using BLACKENED’s proprietary BLACK NOISE™ sonic enhancement process. During finishing, the whiskey undergoes a sonic enhancement process in which the finishing barrels are pummeled by the low hertz frequencies of Metallica’s music. The sound waves cause vibrations that shake the finishing barrels, causing greater interaction between the whiskey and the wood, extracting more flavors and color. This expression is bottled at cask strength and is non-chill filtered.
